SPRING-BED.V

SPECIFICATION forming part of Letters Patent No. 473,729, dated April26, 1892. Application ilecl December 12, 1891. Serial No. 414,792.(Nomodel.)

To LZZ whom it may concern.-

Be it known that I, HERBERT L. DAY, acitizen of the United States, and aresident of Cherrylield,in the county of lVashington and State of Maine,have invented certain new and useful Improvements in Spring-Beds; and Ido hereby declare that the followingis a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, referencebeing hadto the accompanyingdrawings, which form a part of this specification,and in whicl1- Figure 1 is a perspective view of my improved spring-bed,looking at it from the under side. Fig. 2 is a longitudinal sectionalview of the same. Fig. 3 is a transverse sec tional view on line co inFig. 2. Figl is an end elevation, and Fig. 5 is a detail perspectiveview.

' Like letters of reference denote correspondi ing parts in all thefigures.

My invention relates to springbeds; and it consists in the improvedconstruction and novel combination of parts of a bed of that type whichwill be hereinafter more fully described and claimed.

Referring to the accompanying drawings, the letter A designates thebottom slats,which are connected to one another at the head and bottomof the bed by the transverseV pieces B B, thus forming a rectangularframe of suitable size to iit the bed. Upon the longitudinal slats A Aare fastened the coiled springs C, arranged in parallel rows andpreferably placed a little farther apart at the front end than at thehead, the superimposed weight of a person reclining on the bed beingless at the foot than at the head. The tension of each spring C isregulated by means of chains D, connecting one or more of its coils withthe bottom slats, thereby equalizing the tension or upward pressure ofall the springs, and in order to maintain the upright position of thesprings and prevent them from tilting side- Wise these are connected toone another by chains E, attached to and connecting their upper coils.

'lo the foot end of the bottom frame is rigidly fastened a narrowfoot-board F, and upon each of the slats A, at thehead end, is fasteneda coil-wire tension-spring G, the upper legs or free ends ot' which arefastened to the head-piece or bolster-piece H. To this bolster-piece istacked one end of a stout cover I, of canvas, duck, or other suitabletextile fabric, the other end of which is tacked to the rigid foot-boardF. This cover I is drawn tight and taut across the top of the springsand is maintained in this position by the operation of thespring-actuated Vhead-piece H, the springs G of which operate to forceit outwardly, so as to exert a longitudinal pull upon the flexible coverI, and thereby always keep it taut and even over the top of the springswithout sagging in the spaces between them. The cover I is made widerthan the width of the top of the bed, so as to overlap the same on bothsides, the overlapping edges J being turned down on both sides over theupper coils of the side springs and maintained in this position by beingtacked to the ends of the yielding head-board H and rigid footboard F,as shown at K.

By this construction and combination of parts the flexible cover I willat all -times be held perfectly taut, so as to cover the springs evenly,the turned-down edges J .I preventing the cover from sliding sidewiseupon the top of the springs when a mattress or tick is placed upon orremoved from the bed. The cover cannot sag in the spaces between thesprings, and will thus support the superimposed mattress evenly at allpoints, thus not only preventing undue wear and tear of the lnattress,but contributing very materially to the ease and comfort of the personoccupying the bed.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination, in a spring-bed,of the bottom frame consisting of the longitudinal slats A andtransverse slats B, the rigid or stationary foot-board secured to slatsA, the end springs G, secured to slats A and to the movable head-boardH, the coiled springs C, connected together at their upper ends bychains E and secured to slats A, the chains D, Secured to said slats andto the springs C intermediate their ends, and the flexible coverfastened at one end to the rigid foot-board I and at the other end tothe yielding heedboerd and overlapping the upper coils of the springs Cat opposite sides, substantially es described. i

In testimony that I claim the foregoing as my own I have hereunto afiXedmy signature Io in presence of two Witnesses.
